Artifacts retention and auto clean up (#26131)

Currently, Artifact does not have an expiration and automatic cleanup
mechanism, and this feature needs to be added. It contains the following
key points:

- [x] add global artifact retention days option in config file. Default
value is 90 days.
- [x] add cron task to clean up expired artifacts. It should run once a
day.
- [x] support custom retention period from `retention-days: 5` in
`upload-artifact@v3`.
- [x] artifacts link in actions view should be non-clickable text when
expired.
